2020 Peugeot Expert S L1 Bluehdi 1.5L Diesel · KN70 UBA

A persistent pattern of exhaust emission failures and engine management light malfunctions defines the mechanical history of this vehicle, with failures recorded in 2023, 2024, 2025, and again in July 2026. While the vehicle ultimately passed its most recent test on 13 July 2026, the repeated nature of these defects suggests chronic issues with the emissions control system. The recorded mileage of 77,785 miles represents a high annual accumulation rate of approximately 12,964 miles per year. This level of usage typically results in accelerated wear on drivetrain components, suspension bushings, and braking systems compared to lower-mileage examples. The consistent annual testing interval indicates the vehicle has remained in active service without significant periods of dormancy. Given the history of failures regarding the offside front lower suspension ball joint and the anti-roll bar linkage, a test drive should focus on the front end. Listen for knocking or clunking sounds when traversing uneven road surfaces or during low-speed manoeuvring. The previous advisory regarding oil misting on the nearside rear shock absorber warrants a physical inspection for active leaks, as this can lead to degraded damping and instability. The recurring exhaust emission failures and engine management light issues necessitate a close check of the dashboard for any active warning lamps and a verification of the engine's idle smoothness. Pay attention to any unusual smells from the exhaust or a lack of power during acceleration, which may relate to the previously flagged emissions defaults. Additionally, check for pedal judder or reduced braking efficiency, reflecting the previous advisory for thin rear brake pads.
